Adaptations & survival

Grade 3 · Science · Free lesson

Hi! Let's explore how living things survive in their homes.

Plants have special parts to help them live. Roots take in water from the dirt. Leaves use sunlight to make food for the plant.

Let's compare two different plants. A cactus has long roots to get deep water in the desert. A lily pad has wide leaves to float and catch light on water.

Animals also have body parts and actions to get food, water, and air. A hawk uses sharp claws to catch food. A fish uses gills to breathe air from water.

Fish Gills Take In Air
✏️ Worked example

Compare how a desert camel and a river otter take in food and water to survive.

  1. Look at the camel. It drinks a lot of water at once and stores energy in its hump.
  2. Look at the otter. It uses sharp teeth to catch fish in the river.
  3. Compare their body parts: Camels store energy for dry places. Otters use sharp teeth for quick swimming food.
  4. Explain: Both animals have special body structures that help them get food and water in their unique homes.
